The Problem
 Manually maintaining the permission
configuration of SVN or CVS+ACL is
error prone and requires system
administrator privileges
 Permission management of individual
SVN/CVS “projects” should be delegated
to the project owner.

3. © ]project-opem[ 2010, ALM / Frank Bergmann / 3
The Solution
1. Use ]project-open[ as a Web-front-end to
manage the configuration.
2. Model the SVN/CVS projects in ]po[ as
configuration items.
3. Assign the SVN/CVS project owners as
administrators to the ]po[ configuration items
representing the CVS/CVS projects
4. Use a Perl script (or any other language) to
generate the SVN/CVS configuration files
based on the ]po[ configuration. The Perl
script can use the ]po[ REST interface to
query a remote ]po[ server

The Solution
 On the ]project-
open[ server, a REST
interface exposes the
SVN/CVS configuration
as a Web service
 On the SVN/CVS server,
the Perl script retrieves
the configuration and
writes the configuration
files for the SVN/CVS
daemon

Group Management for CVS + ACL
 CVS+ACL (cvsacl.sourceforge.net/) is a
patch for CVS that adds ACLs (Access
Control Lists) permissions to CVS
 A “CVS ACL Group Admin” portlet (at
the right) is shown in the ]
po[ UserViewPage. It allows to manage
the user’s CVS group membership.
 The CVS ACS portlet is integrated into
the ]po[ permission system, allowing to
delegate permissions.
 A Perl client uses the ]po[ REST
Interface to retrieve the group
information and writes the
CVSROOT/group configuration file
 The example at the right shows the
resulting “group” file for CVS+ACL
generated by the Perl client.

Installing Group Management for CVS + ACL
 Make sure you are running ]po[ 3.5 or higher
 Retrieve the package “intranet-cvs-integration” from
the ]po[ CVS server (=> see www.project-open.org for
details)
 Install the package using /acs-admin/apm/ -> Install
packages
 You will see the CVS Group Admin portlet in every
user’s page
 Go to the Perl directory ~/packages/intranet-rest/perl-
client-examples/ and run “perl generate-cvs-acl-group-
conf.perl”
 For questions and issues please go to
